I'm using chrome://net-internals/#hsts to do HSTS testing.
I tried to query a domain that has HST preloaded (facebook.com), and got the expected results:
Found: static_sts_domain: facebook.com
However, I tried the following steps with a domain that is not preloaded (live.com)
Go to http://live.com (I then get redirected to https://live.com)
Query live.com domain for HSTS (using
chrome://net-internals/#hsts) Results: Not foundGo to https://live.com (directly typing HTTPS to avoid being redirected)
Query live.com domain for HSTS (using
chrome://net-internals/#hsts) Results: Found: dynamic_sts_domain: live.com
I don't understand why my query at step 2 didn't find anything. I got redirected, but I ultimately visited https://live.com and received a response that contained an HSTS header Strict-Transport-Security:max-age=63072000;includeSubDomains.
